    The cost of Membership is based on the size of your business and is paid on an annual basis. It is a small portion of the level of savings you will receive as an n3 Member. If you’re part of an Association, your Membership fee may already be covered.

    As an n3 Member you will have access to 50+ Suppliers. We have Suppliers in a wide range of categories that can provide you with goods and services including but not limited to stationery, gas, worksafe training, chemicals, hygiene, building supplies and materials, accountancy, safety equipment, tyres, glass, technology, furniture, maintenance supplies, fuel and more.

    Your Membership includes access to the following:

    • Discounts for business purchases through On Account trading and Trade Card for cash purchases
    • Monthly reporting of your spend and save figures
    • Dedicated n3 Account Manager
    • Website access to manage your Membership

    The Trade Card is only to be used for business purchases.

    Let us know who your current Suppliers are – we might already have contracts with them. If we do, we can compare n3 pricing to your current pricing, and we will only link your account if it is beneficial and you will get a better deal. If we don’t have a contract with your current Supplier we may be able to provide an alternative n3 Supplier that you can trade with.

    Once you open or link an account with an n3 Supplier you deal with them directly. Your n3 discounts will be automatically applied by the Supplier and you will receive a monthly invoice directly from each Supplier for the goods and services you have purchased. It couldn’t be easier!

    Absolutely – we’re always here to help. Email ask@n3.co.nz with your questions and we'll get back to you as soon as we can, or phone 0508 20 30 40 to speak to the n3 team.
